• Remember first Tony's comments earlier this season about getting whacked (which were also replayed the previous week). Tony said, "You don't see it coming; you don't feel nothing; everything just fades to black." That was the ending.
• As for by whom; take note of the credits for the folks in the restaurant at the end.
• Nikki Leotardo: The guy at the counter that goes to the bathroom is Nikki Leotardo, Phil's nephew.
• The Black Men: The black men are the same ones that shot Tony in season two, but only clipped his ear.
• The Boy Scouts: Oddly, the Boy Scouts were in the store last week when Bobby got it, so they are going to have some issues. Is this a sick coincidence?
• The trucker with the USA Hat: There was a trucker wearing a hat that read, "USA." It was his brother that was the trucker that Christopher robbed and killed in season two. He had to identify his brother's body. And the name of this episode was curiously, "Made in America." Why did David Chase pick that crazy title if not to lead us to conclusion that the trucker with the USA Hat was Tony's real assassin? It's all in the credits.
• But Tony was, indeed, whacked. As he died everything abruptly and suddenly ended and cut to black. Everyone else's lives go on. Carmela and AJ must have been screaming seeing Tony be killed. Meadow is just finishing parking and is about to be confronted with her father's death.
